I saw my first '03 2500 w/ a HEMI in it. Are the American Axle's that are now being used smaller than the old Dana's? It looked like a toothpick under there... what's up with that? Are there different options available for the axle or something? Can you get a bigger one? I can't see that holding up under a heavy load... someone explain it to me please!!<br><br>Tony

 

Dodge is putting either 10.5 or 11.5 inch axles in the heavy duty trucks, depending on model. Mine looks plenty big to me but I have the 11.5 inch.<br><br>Casey

 

Ahhhh, thanks for clearing that up. It just looked really small for some reason and I wasn't sure why! ;D<br><br>Tony

 

If you order the 4.10 ratio you myst have anti-slip and the 11.5&quot; axle by AAM.

 

The front axles are smaller than a Dana 60, though, in terms of ring gear size.<br>Chris

 

Front axle is &quot;FRONT AXLE - 9 1/4 AA DESCRIPTION<br>The axle consists of a cast iron center casting differential<br>housing with axle shaft tubes extending<br>from each side. The tubes are pressed into the differential<br>housing and welded. The design has the centerline<br>of the pinion set above the centerline of the<br>ring gear. The axle has full-floating axle shafts,<br>meaning the shaft are supported by the hub bearings.<br>The axle has a vent used to relieve internal<br>pressure caused by lubricant vaporization and internal<br>expansion.&quot; from 2003 Service Manual<br>
